New Delhi, Mar 14 (ANI): The Parliamentary Ethics Committee, headed by veteran Bharatiya Janata Party (BJP) leader Lal Krishna Advani, has issued a show-cause notice to Congress vice-president Rahul Gandhi asking him to respond to questions on whether he had once declared himself a British citizen. Parliamentary Ethics Committee member Arjun Ram Meghwal said it is a very serious matter and the committee would discuss the further course of action once the Congress vice-president responds. He added that a complaint reached the Lok Sabha speaker, which she forwarded to the Parliamentary Ethics Committee. The committee, therefore, issued a show-cause notice asking him to respond to as to how he showed his British citizenship when he was about to become the director of a company in London.
